Climate change has great effect on water resources in the source region of the Yellow River, which affects agricultural productivity, industrial water supply and wildlife management in the whole river basin. The hydrologic characteristics of precipitation, temperature and runoff in the source region of the Yellow River are analyzed using the long-term observed data from 1961 to 2010. The trend of

The purpose of this study is to let a group of addicted mothers who live separated from their children voice their thoughts and experiences through in-depth interviews made in the early 90's. From a perspective of experience of life we look at their living conditions, their everyday life, their experiences of pregnancy, their life with the children, and their life after the separation. What does i

A recently proposed approach to human intention estimation in goal-oriented motion is further improved in this paper. The main features of the approach are the fact that the unicycle model has been rewritten with the natural coordinate as the independent variable, avoiding the explicit dependence from the walking velocity and lowering the number of input variables to one, the proposal of a novel c

A field experiment was carried out to explore the possibilities of planting halophytes on salt-affected land with saline water irrigation. The changes in the salinity of the soil profile, the survival rate and growth conditions as well as the salt tolerance were investigated over a five-year period after the planting of halophyte shrubs and arbours. The results show that halophytes can assimilate

A field study for the arid northwest China has been conducted to find water-saving strategies of drip irrigation for dense-planted crops. The annual water consumption for optimal growth was 420 mm, of which soil evaporation was 27% and the foliage transpiration 73%. A relationship between soil water consumption and the irrigation amount, crop yield and water use efficiency were established. It was

Molecular junctions offer unique opportunities for controlling charge transport on the atomic scale and for studying energy conversion. For example, quantum interference effects in molecular junctions have been proposed as an avenue for highly efficient thermoelectric power conversion at room temperature. Toward this goal, we investigated the effect of quantum interference on the thermoelectric pr

Molecular motor-based nanodevices require organized cytoskeletal filament guiding along motility-promoting tracks, confined by motility-inhibiting walls. One way to enhance motility quality on the tracks, particularly in terms of filament velocity but also the fraction of motile filaments, is to optimize the surface hydrophobicity. We have investigated the potential to achieve this for the actin-m

This study concerns the management functions, institutional and legal frameworks to foster IRBM in the Yangtze River Basin. It is implemented as part of the EU China River Basin Management Programme funded by the EU.The overall objective of the study is to contribute to an enabling framework of policies, legislation and institutions that will promote IRBM in China and assist the government to harm

This monograph is based on the results of the national water pollution control and management technology major special projects “Research on Primary and Secondary Zoning of Songhua River Basin Aqua-Ecological Functions” (Project No: 2008ZX07526-002-01) and “Research on Third and Fourth Zoning of Songhua River Basin Aqua-Ecological Functions ” ( Project No: 2012ZX07501002-01). The outcomes of this

The book "Aqua-ecologic Functional Zoning of Songhua River Basin: Application Manual" introduces the technical methodology and detailed application instructions for aqua-ecologic functional zoning in Songhua River Basin in a systematic way in nine Chapters. Based on a general introduction of concept and in-depth contents of aqua-ecologic zoning and its methodology, this application manual addresse

New options are needed to reduce the impact of motor vehicles on climate change and declining fossil fuel resources. Cars which are fueled by hydrogen could be a sustainable method of transportation if suitable technologies can be devised to produce hydrogen in an environmentally benign manner along with the provision of the necessary fueling infrastructure. This paper assesses size, space, and co

Around 100,000 refugees are resettled to dozens of countries from conflict zones every year. While there is growing evidence that the initial placement of refugee families profoundly affects their lifetime outcomes, there have been few attempts to optimize resettlement destinations within host countries. We describe how machine learning and integer optimization can be used to empower resettlement

What is new in African economic history? A. G. Hopkins recently presented the “new economic history of Africa” to historians, and argued that it had appeared largely unnoticed by historians of Africa. Since some of the seminal contributions appeared in the early 2000s, there has arguably been a renaissance in African economic history. This chapter discusses some of the challenges of differences in

Introduction: It is well established that managing patients with acute stroke in dedicated stroke units is associated with improved functioning and survival. The objectives of this study are to investigate whether patients with acute stroke are less likely to be directly admitted to a stroke unit from the Emergency Department when hospital beds are scarce and to measure variation across hospitals

We perform a multi-dimensional parameter scan in the generation of high-order harmonics, with the main purpose to find the macroscopic conditions that optimize the harmonic yield in a specific spectral domain, around 40 eV for this particular case. The scanned parameters are the laser pulse energy, gas pressure, interaction cell position relative to focus and the cell length, while the fixed param

Background: Worldwide, about 1.3 million annual ischaemic strokes (IS) occur in adults aged <50 years. Of these early-onset strokes, up to 50% can be regarded as cryptogenic or associated with conditions with poorly documented causality like patent foramen ovale and coagulopathies. Key hypotheses/aims: (1) Investigate transient triggers and clinical/sub-clinical chronic risk factors associated wit
